There are some people that I can clearly think of who do this type of play style however; I think the bottom line are the players themselves. Like what Gondolf had just said, there are some players that just like to do that kind of play style who care more about their kills or specifically to me, kills per map. Sure, there are some who care about getting to the top playing that kind of style, but the ones that I look at are the ones who care about kills per map that are trying to make their KDAs look decent/good.
Even with the point system changed, I think players are still at fault who are performing this type of play style so I think it's fully aware now that us (admins) should be a little bit more strict. The players were warned numerous times to not do it when it clearly was visible and evident however; they still continue to do it sooner or later. Despite some of them being long term players, it's unacceptable because I do agree that it irritates everyone else on the server.
If the point system were to be changed, it'll be up to Toan and Liam to decide on whether or not they want to change it. The RWS system does interest me though, but I have no clue on how it's going to be split between 16 players on each side. I'm very curious, so it does make me wonder if it'll be good or not.

Even so, many of the players are either investing their time into PubG, Destiny 2, or other things in their lives. Holidays, school, work, etc may easily conflict during these times compared to summer where people (or students) tend to have more free time. There's still some time left so perhaps people will start registering their teams in the last minute.
